Abundance of the chemical elements

Based on Physical and Chemical Properties, Determination of Identities of Zinc, Sodium, Beryllium, Copper and Boron By: Shreya Uppala, Lizzy Jolly, and Kyrie Harrell Results: The first element we tested was zinc. Since zinc was already known, the density was stated to be 7.13g/mL and the hardness was a 2.5 based on the Mohs Hardness Scale. No magnetic attraction was observed when in contact with a magnet. Zinc had a shiny appearance with a light gray color and the strips of zinc added to…

interdependent components, function in cycles, so each component or element of the cycle can influence another. Feedback loops are the increase (positive loops) or decrease (negative loops) in a process or component and the fluctuation of any element of the cycle with affect the whole. Different loops interact within ecosystems and create what is referred to as “dynamic equilibrium.” In an elk population, if there is an abundance of elk being born and continuing to reproduce, it will create a…

In the Earth’s crust, there is an abundance of natural resources that civilization seeks in fueling in future with the use of natural gas, oil, etc. Therefore, people have taken the opportunity with new developments such as fracking to essentially extract those natural resources from the very depths of the earth. However, there are potential complications that come with the extraction of natural gas as fracking inputs a vast amount of water, sand, and chemicals into deep layers of earth.…

second element in the periodic table. Its period number is 1 and it is apart of group number: 18. The group that Helium falls under is the Noble Gases. The element has an atomic number of 2, an atomic mass of 4 and is classified as a non-metal. It is the second most abundant element in the universe. Helium was discovered on the sun before it was found on the earth. In 1895, Pierre-Jules-César Janssen, a French astronomer and Norman Lockyer, an English astronomer both who discovered the element…

fish and plankton in the ocean. Without potassium, the ninetieth element on the periodic table with chemical symbol “K,” life would be immensely different today, notwithstanding any in the first place. Potassium functions a significant role in lives, more specifically, its ions and compounds. Indeed, potassium is everywhere, but certainly not as a free element due to its highly reactive property. As the seventh most abundant element on earth, potassium remains crucial for life and humanity…

). It is most commonly used in the creation of fertilizers. The original problem that led to the use of this chemical was the increasing population and larger demand for food which meant farmers needed to grow higher yield crops at a faster rate. Fertilizers were heavily used to provide nutrients with ingredients such as nitrogen, phosphorus, potassium, which are essential chemical elements for plant growth and increases growth rate and photosynthesis…

able account for the fact that life emerged roughly 3.8 billion years ago, the short time gap between the formation of oceans and the origin of life, and the chemical composition of modern day cells (Baross and Hoffman, 1985).…

in the life of Romans and the results of their use. According to Kamm, A. (2008), the introduction of some of the very basic elements in Roman architecture, especially the dome, the arch, the vault and the use of concrete were the elements that really began to set the Romans and their style apart from others. In this paper the focus is on the main two essential elements, the arch and concrete. With the invention of Roman concrete, this enabled buildings such as the Pantheon to continue to stand…

Rain is already slightly acidic originally and has a pH of 6 without being introduced to acids in our atmosphere.This is because as rain falls it combines with carbon dioxide CO2 to form carbonic acid H2CO3 which is a very weak acid and completely harmless in our environment. When acids are introduced into the rainwater it can lower the pH of rain to 3, this is very acidic according to the pH scale. The lowering of pH is 10-fold. This means that lowering the pH from 6 to 3 you must do 10x10x10…

This oil painting shows an adroit apiarist, which simply means skilled beekeeper, getting ready to use a bee smoker on a hive of bees. The smoke is filled with chemicals that render the bees incapable of defending their honey. The passiveness of the bees is echoed in the rest of the elements of nature in the photo. These other elements of nature are receiving the same treatment by humans, yet they remain submissive. In the background you can see crops and trees killed and depleted of their…
